Incompatible object file with sparc output

[andreadimax]

Hi!

Trying to compile your identical Rust file with the options for sparc-unknown-none-elf in the TOML file you specified resulted me in a linker error:

C:\Software\sparc-bcc-2.3.1-llvm\bin\sparc-gaisler-elf-ld: unknown architecture of input file C:\Users\andrea\AppData\Local\Temp\rustcWVygff\symbols.o' is incompatible with sparc output

As you can see I use bcc-2.3.1-llvm from gaisler and rustc 1.83.0-nightly

Can you help me?

Do you see the same issue with the latest nightly?

[andreadimax]

Unfortunately I can't use the latest :(

Unfortunately I can't triage issues in a Tier 3 target that isn't the latest nightly. There were a bunch of known issues with the SPARC target a while back but I think we got them fixed. As far as I know RTEMS still runs a canary build and it's still working.

Ferrous Systems can offer professional support for this target if required. You can reach out via https://ferrous-systems.com/contact/.

I solved adding the option "-Wl,--accept-unknown-input-arch" for the linker. Happy to share with you that I succesfully run Rust on TSIM LEON4 emulator! Thank you!

Unfortunately that doesn't actually fix rust-lang/rust#130172. You're just including the wrong machine code into your final binary.
